Research On The Electrical Characteristic Of Memristor By Virtual Simulation

The memristor is a passive two-terminal non-linear element,and it has the ability to remember the flowing current. Memristor are electrical resistance switches that can retain a state of internal resistance based on the history of applied voltage and current. Memristor can fast remember a large number of continuous data, which make them promising candidates of faster, low-energy computer. It will greatly simplify the chaos circuit structure, and also improved the performance of large-scale integrated circuit. The memristor is still able to retain the information, while turning off the power. So, the memristor is challenging the flash of common digital devices, and, it became a research topic of new storage technology.Memrisitor has aroused widespread interests because of its unique electrical properties and considerable prospect.Recently, memristor studies have encountered two main problems.Firstly, the microscopic nature of electrical switching is still under debate.Secondly, the memristive properties are not stability under the same conditions.An ideal memristor with a Pt /TiO2/ Pt sandwich structure were researched by a virtual simulation method. The main research results are as follows:1. We design, write and debug simulation programs and finish the mathematical modeling of memristor based on memristor relevant principles and basic algorithms, as well as the ideal model and related data.2. We discuss the impact of various factors on memristor such as doped region length, input waveform and excitation frequency, and so on.In our simulation programs, the parameters are controllable and adjustable, and the output is ideal. The simulation results confirm to the electrical characteristics of the memeristor. Simulation platform interface can optimize the structure parameters and form a macro-control of memrisor. It becomes a new tool and provides a theoretical guidance for researcher.
